我试图编译一个项目，我最近开始工作，并要求编译代码的铿锵而不是GCC。 目前该项目的CMake的文件中，我尝试使用到C进行项目
cmake -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ../src
然而抛出一个错误，我相信这是因为铛没有一个Fortran编译和项目的一部分，具有Fortran代码。 有没有一种方法，使之使用gfortran编译Fortran代码时（使用GCC时之前使用），和铛/铛++的休息吗？
CMake的文件我认为部分相关的是：
enable_language(Fortran)
string(REGEX MATCH gfortran HAVE_GFORTRAN ${CMAKE_Fortran_COMPILER})
string(REGEX MATCH xlf HAVE_XLF ${CMAKE_Fortran_COMPILER})
string(REGEX MATCH pg77 HAVE_PG77 ${CMAKE_Fortran_COMPILER})
string(REGEX MATCH g77 HAVE_G77 ${CMAKE_Fortran_COMPILER})
string(REGEX MATCH ifort HAVE_ifORT ${CMAKE_Fortran_COMPILER})
string(REGEX MATCH f77 HAVE_F77 ${CMAKE_Fortran_COMPILER})
if(HAVE_GFORTRAN)
set(F_LIBRARY gfortran CACHE string "fortran library")
find_library(F_LIBRARY NAMES gfortran)
set(FORTRAN_UNDERSCORE end CACHE string "What type of fortran underscore style - linux,end,none")
set(DEF_FORTRAN_UNDERSCORE "#define FORTRAN_UNDERSCORE_END")
elseif(HAVE_XLF)

set(FORTRAN_LIBRARY "" CACHE string "fortran library")
set(DEF_FORTRAN_UNDERSCORE "#define FORTRAN_UNDERSCORE_END")
endif()
# f77 on redstorm currently an exception - doesn't need it
if(NOT F_LIBRARY AND NOT HAVE_F77)
message(FATAL_ERROR "Cannot find fortran library")
endif(NOT F_LIBRARY AND NOT HAVE_F77)
终端输出说，当我试图cmake的，这是抛出一个错误：
message(FATAL_ERROR "Cannot find fortran library")
请让我知道，如果我需要张贴任何更多的信息。 提前谢谢了！
