Please remember to send this to the cmake list as well. There are
experts who should be better help than me..

Here's my sample project,

C:\Users\gneill\Desktop\test\build>cat ..\CMakeLists.txt
CMAKE_MINIMUM_REQUIRED(VERSION 2.4 FATAL_ERROR)

IF(COMMAND cmake_policy)
 CMAKE_POLICY(SET CMP0002 OLD) # duplicate target names
 CMAKE_POLICY(SET CMP0003 OLD) # bare lib linker searches
 CMAKE_POLICY(SET CMP0005 OLD) # escaping on macros
 #  CMAKE_POLICY(SET CMP0010 OLD)
ENDIF(COMMAND cmake_policy)

SET(INSTALL_BIN_DIR  "bin")
SET(INSTALL_LIB_DIR  "lib")
SET(INSTALL_MAN_DIR  "man/doc")

ADD_EXECUTABLE(test test.c)

INSTALL(TARGETS test
 RUNTIME DESTINATION "${INSTALL_BIN_DIR}"
 LIBRARY DESTINATION "${INSTALL_LIB_DIR}"
 ARCHIVE DESTINATION "${INSTALL_LIB_DIR}"
)

FILE(GLOB CFILES "${THIRD_PARTY_PATH}/doc/*.txt")

INSTALL(FILES ${CFILES} DESTINATION "${INSTALL_MAN_DIR}")


Later,
George.
