CMAKE SET DEFAULT INSTALL
The -target option with install parameter in addition to the -build option tells cmake to build the install target. After LLVM has finished building, install it from the build directory: cmake -build. Or if it was an invalid generator CMake will choose its internal default generator. The underlying build tool can be invoked directly, of course, but the -build option is portable. DCMAKE_TOOLCHAIN_FILE=/./64bit.toolchain TLDR: CMake 3.15 and above uses the environment variable CMAKEGENERATOR as the default generator, it'll be used by cmake if no -G option provided.
CMAKE SET DEFAULT 64 BIT
If you want to build your 3rd party ExternalProject_Add with 64 bit architecture - just pass toolchain to CMAKE_ARGS: ExternalProject_Add(ĬMAKE_ARGS.
CMake can honor default C++ standard of the compiler if its greater than C++11 You can clearly specify whether C++ standard is. Now I also want to add one for windows as well to compile with mingw. For both 32 and 64 systems i have separate chroots. Make sure you dont accidentally overwrite the contents of CMAKECXXFLAGS later on. I use cmake on linux for cross-compilation. If you want to build two projects - just use same toolchain: cmake -Hproj-1 -B_builds/proj-1 -DCMAKE_TOOLCHAIN_FILE=/./64bit.toolchainĬmake -Hproj-2 -B_builds/proj-2 -DCMAKE_TOOLCHAIN_FILE=/./64bit.toolchain The SET(CMAKECXXFLAGS '-stdc++0x') works fine for me, so there is probably a problem somewhere else in the CMakeLists file. a tool chain (-DCMAKE_TOOLCHAIN_FILE=64bit.toolchain).If it is set to all, all configurations from CMAKECROSSCONFIGS are used.
It's not possible to do it with CMAKE_BUILD_TYPE (at least, again, in a scalable fashion). Specifies a semicolon-separated list of configurations to build for a target in build.ninja if no :option (BUILDSHAREDLIBS 'Build using shared libraries' ON) Next, we need to specify output directories for our static and shared libraries. We use the option () command as it allows users to optionally select if the value should be ON or OFF. Also I'm sure you have to adapt find_package behaviour by setting some *_ROOT CMake variables. To accomplish this we need to add BUILDSHAREDLIBS to the top-level CMakeLists.txt. But in my opinion you're mixing unrelated stuff.
