Unfortunately, the standard values for CMAKE_BUILD_TYPE only have their
first letter capitalized, i.e. for a release build CMAKE_BUILD_TYPE will
normally be "Release". To use it like you want to, it would need to be
"RELEASE". To get around this problem, we define an all upper-case
BUILD_TYPE in our projects, i.e.:
string(TOUPPER ${CMAKE_BUILD_TYPE} BUILD_TYPE)
message(STATUS "CXX compiler ${CMAKE_BUILD_TYPE} build options:
${CMAKE_CXX_FLAGS_${CMAKE_BUILD_TYPE}}")
If you do this, keep in mind what fdk17 said - CMAKE_BUILD_TYPE may not
be set depending on the generator you use.

Hello,
I try to print CMAKE_CXX_FLAGS_DEBUG/CMAKE_CXX_FLAGS_RELEASE as one
line statement but is does not work for me:
message( STATUS "CXX compiler ${CMAKE_BUILD_TYPE} build options:
${CMAKE_CXX_FLAGS_${CMAKE_BUILD_TYPE}}")
Produce empy result, but
message( STATUS "CXX compiler Release build options:
${CMAKE_CXX_FLAGS_RELEASE}")
works as expected.
Is it possible to do it in one line or I have to use if/elseif ?
