cmake在linux上覆制fortran模塊失敗

Question

我有一個使用cmake構建的fortran代碼版本。目前它正在Mac OS X上工作，但是當我嘗試在Linux上構建它時，它失敗了。 Cmake成功生成makefile，但是當我嘗試運行makefile時，嘗試複製模塊時失敗。

頂級cmake的文件是：

cmake_minimum_required (VERSION 2.8) 

# Start Project and note the language used. 
project (v3fit_suite Fortran) 

# Set a directories to build all binary files. 
set (EXECUTABLE_OUTPUT_PATH ${CMAKE_CURRENT_SOURCE_DIR}/build/bin) 
set (LIBRARY_OUTPUT_PATH ${CMAKE_CURRENT_SOURCE_DIR}/build/lib) 

# Fortran specific settings. The first setting tells the compiler to use the C preprocessor. The second places a common directory to place all of the module files. 
set (CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -cpp") 
set (CMAKE_Fortran_MODULE_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/build/modules) 

# List all the subdirectories these are in library dependancy order. 
add_subdirectory (LIBSTELL) 
add_subdirectory (VMEC2000) 
add_subdirectory (V3FITA) 
add_subdirectory (MAKEGRID) 
add_subdirectory (V3POST) 
add_subdirectory (V3RFUN) 

所有模塊應該被複制到構建/模塊。當我運行在Linux上使用詳細的Makefile文件= 1，我得到：

我使用gfortran作爲我的編譯器，而不是f95的時候有同樣的問題。爲什麼在Mac OS X上工作但在Linux上失敗？在Mac OS X上，我安裝了2.8.8版本的cmake和Linux版本2.8。

原來有一個看似無關的錯誤導致了問題。我有一些語句來添加一個空的包含路徑。

find_library (NETCDF_F netcdff PATHS ${NETCDF_LIB_PATH}) 
find_file (NETCDF_I netcdf.inc ${NETCDF_INC_PATH}) 
if (NETCDF_C AND NETCDF_F AND NETCDF_I) 
    message (STATUS "Using netcdf") 
    set (CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -D NETCDF -I ${NETCDF_INC_PATH}") 
endif() 

即使'NETCDF_INC_PATH'爲空時，if語句總是顯示爲true。這在編譯器命令行中導致了一個額外的-I，它將所有東西搞砸了。
