target_sources since CMake 3.13 works with targets in other directories. target_sources() is noted to work with generator expressions.

17.12.2014 · この2つのプロパティは Generator Expressions と特に相性がよいでしょう。 おわりに. 以上、Generator Expressions でした。Generator Expressions はクセのある機能ですが、うまく使うと便利でしょう。 明日は、mrk_21 さんの『CMake: CTest』です。

Generator expressions are evaluated during build system generation to produce information specific to each build configuration. Generator expressions are allowed in the context of many target properties, such as LINK_LIBRARIES , INCLUDE_DIRECTORIES, COMPILE_DEFINITIONS and others.

Output-Related Expressions Debugging Introduction ¶ Generator expressions are evaluated during build system generation to produce information specific to each build configuration. Generator expressions are allowed in the context of many target properties, such as LINK_LIBRARIES, INCLUDE_DIRECTORIES , COMPILE_DEFINITIONS and others.

Mar 01, 2021 · CMake Processing Stages The first step to understanding generator expressions is to get a solid grasp on the CMake build process. Most of the time this is simplified to two distinct stages: configuration – when cmake is executed on the project build – when the generated build system is ran in the build directory

15.02.2021 · Ah, the embedded ; in the genex element confuses the list parser. I would just add the genex entries directly to the target_compile_options command instead of using an intermediate variable. CMake’s list encoding is not really that …

Generator expressions can be nested, as shown in most of the examples below. Boolean Generator Expressions ¶ Boolean expressions evaluate to either 0 or 1. They are typically used to construct the condition in a conditional generator expression. Available boolean expressions are: Logical Operators ¶ $<BOOL:string> ¶ Converts string to 0 or 1.

harder than expected. You should be able to do this without generator expressions and just. CPACK_PROJECT_CONFIG_FILE [1] and CPACK_BUILD_CONFIG [2]. If you really do require/want generator expressions you should be able. to combine that with file (GENERATE) and include ().

generator-expressions are really powerful, but a bit odd and specialized. Most CMake commands happen at configure time, include the if statements seen above.

12.09.2017 · CMake does first parse the CMakeLists.txt files in your project - named "Configuration Phase" - and then it generates your build environment - named "Generation Phase".. So basically the generator expressions are for everything only the generator could know: The name and path of target outputs (mainly when cross-compiling and in multi-configuration …

03.02.2021 · A lot has been said about CMake as undoubtedly CMake is a great tool. If you search “CMake” you will definitely come across this sentence: “CMake is not a build system but rather it is a build system generator”. This blog post is entirely about what CMake generators are, why CMake supports so many of them, and when will you need each of them in your …

Feb 29, 2016 · While generator expression is stored at configuration stage (when corresponded CMake command is executed), evaluation of generator expressions is performed at build stage. This is why message () command prints generator expression in non-dereferenced form: value denoted by the generator expression is not known at this stage.

01.03.2021 · One CMake feature that I feel like raises more eyebrows and causes more confusion than the others are generator-expressions. This may be due to the fact that they are a relatively recent addition to the language, and as a consequence not much relevant tutorial material is …

Programming in CMake Control flow. CMake has an if statement, though over the years it has become rather complex. There are a series of all caps keywords you can use inside an if statement, and you can often refer to variables by either directly by name or using the ${} syntax (the if statement historically predates variable expansion). An example if statement:
