How to set a CMake option() at command line
CmakeCmakelists OptionsCmake Problem Overview
I created a CMakeLists.txt that contains the following
project(P4V)
cmake_minimum_required(VERSION 2.6)
option(BUILD_STATIC_LIBS "Build the static library" ON)
option(BUILD_SHARED_LIBS "Build the shared library" ON)
option(BUILD_TESTS "Build test programs" OFF)
include_directories(${CMAKE_SOURCE_DIR}/include)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/lib)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/bin)
set(CMAKE_BUILD_TYPE Release)
add_subdirectory(src)
if(BUILD_TESTS)
add_subdirectory(tests)
endif(BUILD_TESTS)
By default BUILD_TESTS is OFF, how can I turn it ON without CMake GUI, but with cmake command itself? I tried the following, but it doesn't work
cmake .. -G %1 -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DBUILD_TESTS=ON
Cmake Solutions
Solution 1 - Cmake
Delete the CMakeCache.txt file and try this:
cmake -G %1 -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DBUILD_TESTS=ON ..
You have to enter all your command-line definitions before including the path.
Solution 2 - Cmake
An additional option is to go to your build folder and use the command ccmake .
This is like the GUI but terminal based. This obviously won't help with an installation script but at least it can be run without a UI.
The one warning I have is it won't let you generate sometimes when you have warnings. if that is the case, exit the interface and call cmake .
Solution 3 - Cmake
this works for me:
cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..
