![]() I am afraid that this can change from app to app in respect to which module I need or in respect of the dependecies tree in the modules itself so I'm looking for a cleaner solution. If set to a high-level SDK such as aws-cpp-sdk-transfer, BUILDONLY resolves any. ![]() You could replace for example by and of course pass a value that is a C string literal. ![]() Whereas is the separator of arguments in CMake. The problem is the character that comes from concatenating the list variable in cmake into a string. Click on the Run button and execute cmake -P set.cmake command in the terminal. and after compilation: builddir/main fname1 lname1 fname2 lname2. So I have tried to add it in some module that I think could be nested and hidden in some dependencies but compiling all the application I suddenly faced with: CMake Warning (dev) at /path_to_repo/cmake/FindFooX.cmake:6 (set):Ĭannot set "LIB": current scope has no parent. General CMake Variables and OptionsAndroid CMake Variables and Options. To set a variable, we simply call set(), providing its name and the value. For bypass this I have to add PARENT_SCOPE in the set). Note that in previous examples variable was set on configure step: usage-of-variables> rm -rf builds usage-of-variables> cmake -Henv-configure -Bbuilds Environment variable ABC: 123 - Configuring done - Generating done - Build files have been written. So in one of the final applications that uses some modules I can just do: target_link_libraries($/include)īut it happened sometimes that some module require another modules so that the add_subdirectory creates new scopes and can correctly load LIB but cannot write it (when I use set it is in the deeper scope and not changes the upper scope). Child process will inherit environment variables of parent: 3.6.3.5. If you want to set a variable from the command line, CMake offers a variable cache. IE the macro will only be added to your exe/library. The reason you should prefer this approach over any other approach is because it granularity is target based. You can obtain your COMPILERID on this page. I have a cmake project in which I have some modules and I'm using Find-*.cmake for including the shared modules in the application.įor not taking in account every module that I add, I have defined a kind of global LIB variables tor the linker: # inside a Find-*.cmake or in the CMakeLists.txt of the modules: The names of variables are usually all caps, and the value follows. If you are using CMake 3.X your first choice for adding a preprocessor macro should be targetcompiledefinitions. cmake -DNAMEZLIB -DCOMPILERIDGNU -DLANGUAGEC -DMODECOMPILE -find-package Example to display the libraries: cmake -DNAMEZLIB -DCOMPILERIDGNU -DLANGUAGEC -DMODELINK -find-package The NAME must be set to the package name.
