CMake: how to add Boost.Test cases with relative directories?

Question

I have a working project with CMake and Boost.Test with a directory structure like this (pardon the ASCII art):

+-proj
|---CMakeLists.txt
|---build
|---test
         


        

Answer 1

A possible solution to disambiguate names in a directory structure like the one you have using a FOREACH() over ${test_cases} may be:

# Set Cmake version and policy
CMAKE_MINIMUM_REQUIRED( VERSION 2.8.7 )
CMAKE_POLICY( VERSION 2.8.7 )

PROJECT( DUMMY CXX )

FILE( GLOB_RECURSE test_cases FOLLOW_SYMLINKS "test/*.[h,c]pp" )

FOREACH( case ${test_cases} )
  ## Get filename without extension
  GET_FILENAME_COMPONENT(case_name_we ${case} NAME_WE)
  ## Get innermost directory name
  GET_FILENAME_COMPONENT(case_directory ${case} PATH)
  GET_FILENAME_COMPONENT(case_innermost ${case_directory} NAME_WE)
  ## Construct executable name
  SET( exe_name "${case_innermost}_${case_name_we}")
  ## Construct test name
  SET( test_name "${exe_name}_test")
  ## Add executable and test
  ADD_EXECUTABLE( ${exe_name} ${case} )
  ADD_TEST( ${test_name} ${exe_name} )
ENDFOREACH()

As you can see this CMakeLists.txt creates 4 distinct test/executable couples.
