FindPkgConfig with set_target_properties is unusable for setting CFLAGS/LDFLAGS

由 旧街凉风 提交于 2019-11-27 04:53:09
问题 pkg_check_modules from FindPkgConfig gives MYLIBRARY_LDFLAGS and MYLIBRARY_CFLAGS that are ordinary CMake lists (with semicolon-separator). The set_target_properties and set_property accept just one string. So that doesn't work because it doesn't expand the list: set_property(TARGET ${PROJECT_NAME} APPEND PROPERTY LINK_FLAGS ${MYLIBRARY_LDFLAGS}) This gives same thing with the semicolons inside: set_property(TARGET ${PROJECT_NAME} APPEND PROPERTY LINK_FLAGS "${MYLIBRARY_LDFLAGS}") set_target

PKG_CHECK_MODULES considered harmful?

Various developers discourage the usage of the PKG_CHECK_MODULES (for example, in this answer ) but there is no clear, comprehensive explanation of their reasons as far as I've looked for. So, I ask: Why would PKG_CHECK_MODULES be harmful? What are the alternatives? I, for one, used it for the first time today. I found it invaluably useful, specially for dealing with pretty intricate library sets, such as GTK+, where I have all these dependencies: -I/usr/lib/i386-linux-gnu/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr

What is the proper way to use `pkg-config` from `cmake`?

问题 Looking around on the net I have seen a lot of code like this: include(FindPkgConfig) pkg_search_module(SDL2 REQUIRED sdl2) target_include_directories(app SYSTEM PUBLIC ${SDL2_INCLUDE_DIRS} target_link_libraries(app ${SDL2_LIBRARIES}) However that seems to be the wrong way about doing it, as it only uses the include directories and libraries, but ignored defines, library paths and other flags that might be returned by pkg-config . What would be the correct way to do this and ensure that all
