condition comparison in if

Code
1

Hi,

i tried to do a short test script to see differences in my system when comparing different conditions.

set(BUILD_SHARED_RUNTIME2 TRUE)
message(STATUS “Boost Linkage Shared: ${BUILD_SHARED_RUNTIME2}”)

if(BUILD_SHARED_RUNTIME2)
	message(STATUS ">>>>>>>>>>>>>>>>>>>>>> Inside bool if")
else()
	message(STATUS ">>>>>>>>>>>>>>>>>>>>>> Inside bool else")
endif()

if(${BUILD_SHARED_RUNTIME2})
	message(STATUS ">>>>>>>>>>>>>>>>>>>>>> Inside {bool} if")
else()
	message(STATUS ">>>>>>>>>>>>>>>>>>>>>> Inside {bool} else")
endif()

As a result on my pc i get

-- Boost Linkage Shared: TRUE
-- >>>>>>>>>>>>>>>>>>>>>> Inside bool if
-- >>>>>>>>>>>>>>>>>>>>>> Inside {bool} else

Other pcs get

-- Boost Linkage Shared: TRUE
-- >>>>>>>>>>>>>>>>>>>>>> Inside bool if
-- >>>>>>>>>>>>>>>>>>>>>> Inside {bool} if

Same behaior is with ON/ OFF.

Does someone has an idea if the code or the usage is wrong. Or if my pc has a setting which others do not have? I am really looking forward if someone can bring some light into the dark.

Thanks and Cheers,
Lars
