[CMake] add_test with --build-and-run fails

[Frank Stappers]

Hi David,

Thank for your information. Indeed the CMAKE_SOURCE_DIR differs.
This gave me a new lead. Following your hint allowed me to compile
the executable, however linking to "a_compiled_lib" was causing
a new problem.

So I've decided to solve the problem differently. Namely by
moving the "add_test" into my test project (after the add_executable) and
put "EXCLUDE_FROM_ALL" on the "test_tgt" (therefore excluding the target
from an all_build). The test project now looks like:

=====
project(test_tgt)
cmake_minimum_required(VERSION 2.6)
include_directories(${CMAKE_SOURCE_DIR}/include1)
add_executable(test_tgt EXCLUDE_FROM_ALL "test.cpp"  )
target_link_libraries(test_tgt     a_compiled_lib)

       ADD_TEST(test_tgt ${CMAKE_CTEST_COMMAND}
          --build-and-test
          "${CMAKE_SOURCE_DIR}"
          "${CMAKE_BINARY_DIR}"
          --build-generator "${CMAKE_GENERATOR}"
          --build-project test_tgt
          --build-makeprogram "${CMAKE_MAKE_PROGRAM}"
          --test-command ${CMAKE_CURRENT_BINARY_DIR}/test_tgt
           )
=======

To make it work from the main project, I had change the project back to:

========
.....
ENABLE_TESTING()
add_subdirectory(test)
========

Thank you for help!

Kind regards,
Frank Stappers
