[CMake] Copying files

[ML]

Hi All,

I want to copy the resulting static library I am building to a  
location but I can't see how to do it.

I have:

PROJECT(expat)
CMAKE_MINIMUM_REQUIRED (VERSION 2.6 FATAL_ERROR)
SET(SRCS xmlparse.c
		xmlrole.c
		xmltok.c
		#xmltok_impl.c
)

ADD_LIBRARY(expat ${SRCS})

COMMAND ${CMAKE_COMMAND} -E copy libexpat.a ${PROJECT_SOURCE_DIR}/$ 
{INSTALL_DIR}

What am I doing wrong?
