The configuration installed is determined by the configuration specified
when building the "INSTALL" or "install" target in the build system.
Targets are handled automatically, but for per-configuration files you
have to take advantage of the definition "BUILD_TYPE" that will be
available to the cmake_install.cmake scripts at install time.  For example:

IF(CMAKE_CONFIGURATION_TYPES)
   # ... create the per-config files ...
   SET(inst_from_dir ${whatever}/\${BUILD_TYPE})
ELSE(CMAKE_CONFIGURATION_TYPES)
   # ... create the one-config files ...
   SET(inst_from_dir ${whatever})
ENDIF(CMAKE_CONFIGURATION_TYPES)

INSTALL_FILES(${install_dir} FILES ${inst_from_dir}/foo.cxx)
