Ctest configuration

This replicates issue #115 (closed) , which in turn traces back to !103 (merged), regarding ctest and gtest.

I finally left the project as this (checkout branch frame-base-tests):

• wolf/src/tests --> here all the gtest files are located

• In wolf/CMakeLists.txt

if(BUILD_TESTS)
    enable_testing()
endif()

• In wolf/src/CMakeLists.txt

if(BUILD_TESTS)    
    MESSAGE("Building tests.")
    add_subdirectory(test)
endif()

Added 3 commits:

• 61a11e23 - Typedef derived shared_ptr
• 5c94d449 - [Fix] Put enable_testing() before add_subdirectory(src) fixes the ctest
• cc9ff40c - Add unit tests for FrameBase

Compare with previous version

the last commit did the trick: enable_testing() should be:

• in the root CMakeLists
• before add_subdirectory(src)

with these two conditions everything works.

Unmarked this merge request as a Work In Progress

Status changed to merged
