[CMake] Finding libraries under Windows

[Mike Jackson]

For zlib you can use the FIND_PACKAGE(Zlib). For others you can make  
up your own scripts. I will include the contents of one I wrote to  
find the HDF libraries. Hope it helps out.


#----------------------------------------------------------------------- 
----
# This will find the HDF5 libraries and define the following variables:
#  HDF5_FOUND - Is the base HDF5 library and include file found
#  HDF5_INCLUDE_DIR - The Include directory containing all the HDF5  
include files
#  HDF5_LIBRARY - The Actual HDF5 library
#  HDF5_HL_FOUND - Is the High Level HDF5 API Found
#  HDF5_HL_INCLUDE_DIR - The High Level Include Directory
#  HDF5_HL_LIBRARY - The Actual High Level Library
#  HDF5_USE_HIGH_LEVEL - Set this to TRUE if you need to link against  
the HDF5 High level APIs.
#  HDF_INSTALL - This is an Environment variable that can be used to  
help find the HDF5 libraries and Include Directories
#  HDF5_LIBRARIES - The List of HDF5 libraries that were found. This  
variable can be used in a LINK_LIBRARIES(...) command

#-- Clear the Library List
SET (HDF5_LIBRARIES "")
#-- Clear the include Directories
SET (HDF5_INCLUDE_DIRS "")

# ------------------ START FIND HDF5 LIBS  
--------------------------------------

SET (HDF5_FOUND "NO")
SET (HDF5_HL_FOUND "NO")

FIND_PATH(HDF5_INCLUDE_DIR hdf5.h
     /usr/local/include
     /usr/include
     "$ENV{HDF_INSTALL}/include"
)

FIND_LIBRARY(HDF5_LIBRARY hdf5
   /usr/local/lib

   "$ENV{HDF_INSTALL}/lib"

   ELSE (HDF5_LIBRARY)
     SET (HDF5_FOUND "NO")
   ENDIF (HDF5_LIBRARY)
ENDIF (HDF5_INCLUDE_DIR)

# ------------------ START FIND HDF5 HL LIBS

	MARK_AS_ADVANCED (HDF5_HL_LIBRARY)
