Solaris 11.3上的Sun Studio 12.5。解决一个问题并转到下一个问题...使用CMake构建我们的项目会导致下面的链接错误。
我认为检测SunCC并将-lnsl -lsocket添加到LDLIBS只是一个简单的问题。但是，检测SunCC编译器的方法让我感到厌烦。我发现2006年的一篇旧帖子（来自Error detecting sun studio compiler under linux）：
我正在尝试使用linux下的sun studio编译器而且我正在使用 通过cmake编译器测试的可怕时间。
AFAIK之前没有人用这个编译器尝试CMake .... CMake正在调用编译器，假设它接受其他Linux编译器（如GNU和Intel）接受的标志...你将不得不设置一个平台用于配置此编译器的文件。
我尝试使用CMake Compiler IDs中的SunPro，但会产生如下所示的相同错误。
if(SunPro)
target_link_libraries(cryptopp-shared nsl socket)
target_link_libraries(cryptest nsl socket)
endif()
我的问题是，如何在CMakeList.txt中检测Sun Studio编译器？或者我如何检测Solaris？
