[CMake] cmake + ninja how to use several CPU cores?

Hi, I heard that ninja has great feature it allows build continue without wainting full link. So if you have library Lib and executable App, source code of App may build in parallel with source code of Lib, and sync only link stage. While other build systems force build of Lib, and only then

[CMake] coding style for modules

Hello, If there is some libfoo that I want to use in my project, and this libfoo has it's own CMakeLists.txt I have 3 options to deal with such external dependency: a) Treat it like every other external dependency and write cmake code like FindLibFoo.cmake to find libfoo on file system.

[CMake] crosscompiling: what happened after change cmakelists.txt?

Hi, when I run cmake like this: cmake -DCMAKE_TOOLCHAIN_FILE=toolchain-sdk-gcc.cmake -DMY_TOOLCHAIN_PATH=$HOME/toolchains/sdk/ path/to/CMakeLists.txt with toolchain-sdk-gcc.cmake: SET(CMAKE_SYSTEM_NAME Linux) SET(CMAKE_SYSTEM_VERSION 1) SET(QT_QMAKE_EXECUTABLE ${MY_TOOLCHAIN_PATH}/bin/qmake)

[CMake] status of cmake add_test in current cvs?

During build some executable testA was created, later it was added to list of tests via ADD_TEST. When I used last stable cmake with VS, I have to alawys use hacks like: GET_TARGET_PROPERTY(test_app_path test_app LOCATION) STRING(REGEX REPLACE \\$\\(.*\\) \${CTEST_CONFIGURATION_TYPE}

[CMake] ctest: how to skip tests?

Hi. I have project with usage of cmake and ctest. Now I need to add tests, that may have sense or not have sense to run on certain machine. For example, if we have installed MySql and libmysql there is sense to test part of code working with mysql, but no sense to check parts that working with

[CMake] build type per target?

In my project I have plugin for qt designer, it should be build in release mode, because of in other case qt designer will not load and use it. From other hand I need this code as static library, and use build type the same as my main application uses. So it looks like add_library(some_name

[CMake] cross compiler flags

Usually, I use such construction to set cmake flags: SET(CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG} -Wall but when I use -DCMAKE_TOOLCHAIN_FILE option this construction for some reason does not work, actually, if I run make VERBOSE=1 compiler comand does not contain flags at all, except -c -o
