fix #88 .

[dirk-thomas]

The patch looks good.

Can you please still describe in which case you ran into the problem. So how to reproduce the problem.

[csukuangfj]

@dirk-thomas

A minimum example is as follows:

cmake_minimum_required(VERSION 3.0)
project(test_issue_88)

include(CheckCXXSourceCompiles)
CHECK_CXX_SOURCE_COMPILES("#include<cxxabi.h>\nintmain(intargc,char**argv){}" HAVE_CXXABI_H)
CHECK_CXX_SOURCE_COMPILES("#include<cxxabi.h>\nint main(int argc,char**argv){}" HAVE_CXXABI_H2)

message(STATUS "${HAVE_CXXABI_H}")
message(STATUS "${HAVE_CXXABI_H2}")

Output log

I was referring to how you triggered the problem with the current code of the package.

[csukuangfj]

@dirk-thomas I was reading the source code and found that it set HAVE_CXXABI_H incorrectly, so I proposed the pull request.

Thank you for the patch.
