[cmake-developers] [CMake 0015011]: problem to find non-standard ncurses.h location

[Greg Jung]

The CMake module scripting is weak regarding the variable that should be
taking care of this,
CMAKE_SYSTEM_PREFIX_PATH  (i.e., /usr; /opt)  will be used in find_path
(after appending /include)
and for find_library(after appending /lib) - according to cmake.html
documentation. For my mingw/msys
builds I set this and the /include, /lib mostly located in
platform/MingW.cmake:
----------------
if(MSYS)
# enhance the system prefix path.  (picks up /Mingw/lib)
find_path( MINGWPATH msys
   PATH ${CMAKE_USR_PATH}/../../
NO_DEFAULT_PATH)
 list(APPEND CMAKE_SYSTEM_PREFIX_PATH ${MINGWPATH} )
list(APPEND CMAKE_SYSTEM_INCLUDE_PATH ${MINGWPATH}/include )
list(APPEND CMAKE_SYSTEM_LIBRARY_PATH ${MINGWPATH}/lib )
-------
then LDFLAGS is inspected:
____
set(LDFLAGS "$ENV{LDFLAGS}")
if(LDFLAGS)
message(STATUS "\n"
" <Platform/Mingw> inspecting LDFLAGS: ${LDFLAGS}" )
string( REGEX MATCHALL "-L([^\" ]+)" librarylist
        "${LDFLAGS}" )
foreach(element  IN LISTS librarylist) # LDFLAGS is more specific.
------------ etc., leading to
message(STATUS
"<Platform/Mingw>  adding system library path: ${library}")
list(INSERT CMAKE_SYSTEM_LIBRARY_PATH 0 ${library})
list(INSERT CMAKE_SYSTEM_INCLUDE_PATH 0 ${library}/../include )
-------------------------------------------------------
