In the F&Q Setction there is a excellent example how to handle generated
files in a subdirectory.
The structure is:
mainDirectory (CMakeLists.txt)
+---- ADD_SUBDIRECTORY(src1) (generates the file)
|
+---- Process the file
This works also for this structure
mainDirectory (CMakeLists.txt)
+---- generate the file
|
+---- ADD_SUBDIRECTORY(src1) process the file
>From this I concluded the following structure should be possible
mainDirectory(CMakeLists.txt)
+---- ADD_SUBDIRETCORY(src2) generate the file
|
+---- ADD_SUBDIRECTORY(src1) process the file
Unfortunatelly this generates the make error message:
"There is no rule to generate the target: Name of the generated
file" (Here tm18.c see below)
So really logical is this not.

------------------------------------------
The CMakeLists.txt files
In mainDirectory I have the following CMakeLists.txt file
PROJECT(MainProj)
ADD_SUBDIRECTORY(src2)
ADD_SUBDIRECTORY(src)
In src2 the CMakeLists.txt file looks like this:
PROJECT(T)
CMAKE_MINIMUM_REQUIRED(VERSION 2.4)
CMAKE_POLICY(VERSION 2.6)
ADD_CUSTOM_COMMAND(OUTPUT ${CMAKE_BINARY_DIR}/tm18.c
COMMAND ${CMAKE_BINARY_DIR}/generator tm18
DEPENDS ${CMAKE_SOURCE_DIR}/src/tm
COMMENT "...run")
ADD_CUSTOM_TARGET(targetAdd ALL DEPENDS ${CMAKE_BINARY_DIR}/tm18.c)
and in src2 I have the following CMakeLists.txt file
PROJECT(Tm2)
SET(_targetname ULS)
SET(_src CTest.c ${CMAKE_BINARY_DIR}/tm18.c)
ADD_EXECUTABLE(${_targetname} ${_src})
SET_SOURCE_FILES_PROPERTIES(${CMAKE_BINARY_DIR}/tm18.c PROPERTIES
GENERATED 1)
TARGET_LINK_LIBRARIES(${_targetname} ${GLIB_LIBRARY})
ADD_DEPENDENCIES(${_targetname} targetAdd)
