With the directory structure
/myrepo/tools/aosdesigner
/myrepo/tools/aoslcpp
/myrepo/tools/aoslcpp/test
aosdesigner must be informed about aoslcpp's include directory because
it is not inherited by aosdesigner as it is inherited by aoslcpp/test
since the latter is entered after aoslcpp issued INCLUDE_DIRECTORIES().
Include directories have directory scope whereas regular targets are
global, so you can refer to aoslcpp from aosdesigner's CMakeLists.txt
although the aoslcpp target has been defined in a sibling directory
next to aosdesigner's one, but the same does not work for include
directories. In aosdesigner's CMakeLists.txt, you should use
INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/tools/aoslcpp/include)
or
INCLUDE_DIRECTORIES(../aoslcpp/include)
to make aoslcpp's include directory available for aosdesigner. Note
that if aosdesigner also needs XSD, you should move FIND_PACKAGE(XSD)
to a higher-level CMakeLists.txt file, probably tools/CMakeLists.txt.
'hope that helps.
