我正在尝试在 mac os X 10.11 上编译需要 boost、GMP 和 MPFR 的 plll 库。

我已经通过自制软件安装了 boost、GMP 和 MPFR，然后我在 plll 的 dir build 中启动了 cmake，但我得到了那个错误：

 By not providing "FindMPFR.cmake" in CMAKE_MODULE_PATH this project has
 asked CMake to find a package configuration file provided by "MPFR", but
 CMake did not find one.

 Could not find a package configuration file provided by "MPFR" with any of
the following names:

MPFRConfig.cmake
mpfr-config.cmake

Add the installation prefix of "MPFR" to CMAKE_PREFIX_PATH or set
"MPFR_DIR" to a directory containing one of the above files.  If "MPFR"
provides a separate development package or SDK, be sure it has been
installed.

如果我在 cmake 使用的 Librairies.txt 中更改 GMP 和 MPFR 的顺序，则 GMP 也是如此。

之后，我手动安装了这些库，它们位于/usr/local/include 中。GMP的make检查很完美，所以我猜安装没问题。

但仍然是相同的错误消息。我也尝试添加一个 FindMPFR.cmake 文件，但根本没有任何变化。

这是 Libraries.txt 中涉及的部分：

find_package(MPFR REQUIRED)
include_directories(${MPFR_INCLUDES})
if(NOT MPFR_FOUND)
    message(FATAL_ERROR "Could not find MPFR!")
endif(NOT MPFR_FOUND)
set(libraries ${libraries} ${MPFR_LIBRARIES})
set(libraries_shared ${libraries_shared} ${MPFR_LIBRARIES})

find_package(GMP REQUIRED)
include_directories(${GMP_INCLUDE_DIR})
if(NOT (GMP_INCLUDE_DIR AND GMP_LIBRARIES))
    message(FATAL_ERROR "Could not find GMP!")
endif(NOT (GMP_INCLUDE_DIR AND GMP_LIBRARIES))
set(libraries ${libraries} ${GMP_LIBRARIES})
set(libraries_shared ${libraries_shared} ${GMP_LIBRARIES})

奇怪的是，我对 Boost 没有任何问题……
