Hi,
I'm trying to set up a project pulls in information from another CMake project
(include dirs, libraries, etc.). As I understand it the right thing to do is
create a <Project>config.cmake.in in the source project and then use
find_package in config mode to pull in the information to the dependent project.
So far things seem to be working properly but I'd like to pull the content of
include_directories from the master project into the dependent project because
it has to reference a few headers. I haven't found any built in CMake variable
that collects all the include_directory commands but I can do something like
this:
get_property (dirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY
INCLUDE_DIRECTORIES)
foreach (dir ${dirs})
message (STATUS "MyProject INCLUDE DIRECTORY: '${dir}'")
list (APPEND MyProject_INCLUDE_DIRS ${dir})
endforeach ()
message( STATUS "MyProject_INCLUDE_DIRS: " ${MyProject_INCLUDE_DIRS} )
this seems to do the right thing and lists all the directories in
include_directory() statements, but when I go to the MyProjectConfig.cmake.in
file and have something like this:
set (MYPROJECT_INCLUDE_DIRS ${MyProject_INCLUDE_DIRS})
it doesn't get anything. I have other statements in the
MyProjectConfig.cmake.in file that have a similar pattern and are expanded but
for this one I get something like this:
set (MYPROJECT_INCLUDE_DIRS )
I've used CMake for a while, generated a couple simple project scripts in the
past but this is my first time developing a project using find_package in
config mode. Any suggestions would be helpful :)
Thanks!
-William
