[CMake] Setting IMPORTED_LOCATION_* for existing packages

[Hauke Heibel]

Hi,

I started to work with imported targets and thus with setting the
property IMPORTED_LOCATION and the like. I stumbled over a case
(GTest) where the standard find_package call returns me a list of libs
for 'debug' and 'optimized' modes and I am setting them like this

find_package(GTest REQUIRED)
add_library(GTest UNKNOWN IMPORTED)
foreach(arg ${GTEST_LIBRARIES})
  if("${arg}" MATCHES "^(debug|optimized)$")
    set(_doing "${arg}")
  elseif("${_doing}" MATCHES "^debug$")
    message("setting debug lib to: ${arg}")
    set_target_properties(GTest PROPERTIES IMPORTED_LOCATION_DEBUG "${arg}")
  else()
    message("setting optimized lib to: ${arg}")
    set_target_properties(GTest PROPERTIES IMPORTED_LOCATION "${arg}")
  endif()
endforeach()

I am just wondering whether there is a more simple method to do this.
It looks a bit cumbersome.

Hauke
