Re: [CMake] How to set libcurl library path and the library name?
There is an error in the FindCURL document of Cmake 3.8 (or prior versions). It says CURL_INCLUDE_DIRS - where to find curl/curl.h, etc. CURL_LIBRARIES - List of libraries when using curl. CURL_FOUND - True if curl found. CURL_VERSION_STRING - the version of curl found (since CMake 2.8.8) But in fact it is looking for CURL_INCLUDE_DIR, not CURL_INCLUDE_DIRS. If I set –DCURL_INCLUDE_DIRS, cmake cannot find libcurl’s header files.

Re: [CMake] Overriding the include path, library path of OpenSSL, Zlib and libcurl
Although cmake uses the path I supplied for OpenSSL and Zlib, I do not see the –I flag being used in compiling the code. (I set VERBOSE=1 to make to see what it does.) When I run ‘ldd’ against the resulting .so files, reference to libssl.so or libcrypto.so is empty, i.e ‘libssl.so => not found’, but libz.so still links to /lib64/libz.so. (It seems to ignore the fact it does find a new path of zlib.) How to I set the linker flag, i.e. –L and –Wl,-rpath=$myLibPath ?

Re: [CMake] How to set C++ standard?
Thanks. I find the problem in the source code where it uses CPP_STANDARD as suffix in –std=c++, therefore I should set CPP_STANDARD instead of the other one.

You generally shouldn't set CMAKE_CXX_STANDARD on its own, you should also be explicitly setting CMAKE_CXX_STANDARD_REQUIRED and CMAKE_CXX_EXTENSIONS to ensure you are getting the behaviour you want. These would also typically be set by the project's own CMakeLists.txt file rather than being passed on the cmake command line as cache variables.
