您好，我想让cmake找到dbus-1
当我尝试编译时，我一直收到此错误
-- Checking for module 'dbus-1'
-- No package 'dbus-1' found
我尝试过此命令
pkg-config --cflags dbus-glib-1
我得到了输出
-I/usr/include/dbus-1.0 -I/usr/lib64/dbus-1.0/include -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include
我编辑了CMakeLists.txt并添加了
include_directories(/usr/include/dbus-1.0/)
我在做什么错？？
答案 0 :(得分：0)
The first thing to know about CMake in this situation is don't use the include_directories to include any system directories with a hard-coded path(which is what you are doing now). What you should do instead is use the CMake FindPkgConfig module which will call pkg-config and get those include directories for you.
To do this, something like the following should work.
include( FindPkgConfig )
pkg_check_modules( dbus REQUIRED dbus-1 )
# Add the include directories to our target executable/shared object.
# In this case, our target is called 'executable' and must have been
# created by a previous call to either 'add_executable' or 'add_library'
target_include_directories( executable PUBLIC ${dbus_INCLUDE_DIRECTORIES} )
