Eric Tellefsen:
I am having some trouble with the following.
I have a static library project which has a tree structure of the main
directory and a group of sub directories. The main project has a
CMakeLists.txt file as well as the sub directories. Each of the sub
directories CMakeLists.txt file generates .cpp & .h files from a .wsdl
file via calls to gSoap executables. When make is run, all the sub
directory files are generated into the respective
CMAKE_CURRENT_BINARY_DIR locations, and then compiled by the project
level generated Makefile. All of this works fine.
My seemingly simple problem is as follows. This library and all of
the others being used by my group, I have just converted to CMake and
am using out-of-source builds. Another library depends on the WSDL
(mentioned above) sub directories for header files which are generated
into CMAKE_CURRENT_BINARY_DIR. Unfortunately this inter-library
dependency is looking to the CMAKE_CURRENT_SOURCE_DIR. When this
library builds out-of-source, it cannot find these headers and the
compile fails.
My short-term solution was to copy these files from the respective
BINARY to SOURCE directories using a custom command. This does not
seem to work and I cannot understand why. I've put this code into
both the master CMakeLists.txt as well as the specific subdirectory
CMakeLists.txt file.
Am I taking the wrong approach? Is my syntax for the custom command
incorrect? I'm stumped and could use some suggestions from the group.
Thanks
Eric
Custom command is below
macro( GenericFileCopy Filename FromDir ToDir )
ADD_CUSTOM_COMMAND(
OUTPUT ${ToDir}/${Filename}
COMMAND ${CMAKE_COMMAND} -E chdir ${FromDir} cp ${Filename}
${ToDir}
DEPENDS ${FromDir}/${Filename}
COMMENT "Copying ${FromDir}/${Filename} to ${ToDir}"
)
endmacro( GenericFileCopy )
