我正在使用 Sun Studio 12.5 开发 Solaris 11.3。当我尝试使用 Cmake out-of-tree 进行配置时，Cmake 会出现配置错误并且不会生成 makefile。In-tree 也可能被破坏。但是我们的程序说要在树外构建，所以;' 我所做的。

我几乎没有 Cmake 经验。其他人贡献了 CMake 文件，而我则为与它们相关的任务而苦苦挣扎。我不确定我是否做错了什么，我们的 Cmake 文件是否损坏，或者 Cmake 在 Solaris 下是否经过良好测试。

CMake 发生了什么，我该如何解决？

以下是 Cmake 文件的链接。我可以复制/粘贴它们，但它只占用大量空间。这些文件托管在 GitHub 上，因此它们应该始终可用。

这是 Solaris 的 Cmake 版本，在我安装 3.6.2 之前：

$ cmake --version
cmake version 2.8.6

以下来自 Solaris Cmake 版本 2.8.6。

cryptopp-build$ export CXX=/opt/developerstudio12.5/bin/CC

cryptopp-build$ cmake ../cryptopp

CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCXXCompiler.cmake:45 (MESSAGE):

  It fails with the following output:

和：

$ /opt/developerstudio12.5/bin/CC -V
CC: Studio 12.5 Sun C++ 5.14 SunOS_i386 2016/05/31

我从源代码构建了 Cmake 3.6.2 并安装了/usr/local以解决该CXX compiler identification is unknown问题，但它似乎遇到了一些麻烦。正如我之前所说，我不是 Cmake 专家（而且我不确定如何搞砸 a make && sudo make install）。

cryptopp-build$ cmake ../cryptopp
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/bin
CMake Error: Error executing cmake::LoadCache(). Aborting.

按照@AndrewHenle 的建议清除缓存会导致：

# The project GNUmakefile clears all Cmake artifacts because Cmake cannot seem to do it on its own
$ cd cryptopp
$ git status -s
$

$ cd ..
$ rm -rf cryptopp-build
$ mkdir cryptopp-build
$ cd cryptopp-build

# Using 3.6.2 now
$ cmake ../cryptopp
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/bin

所以出现了两个问题。首先是 Sun 提供的低级 Cmake。将其诊断为“太旧”并不是什么天才。

第二个问题更有趣。看来这CMake Error: Could not find CMAKE_ROOT !!!是由于sudo make install一旦我切换到sudo gmake install问题就消失了。

以下是有关该问题的错误报告：
