Summary0015220: Find_package(Curses) failed for QNX 6.5 and QNX 6.6
DescriptionWhen using find_package(Curses) for a cmake project compiled with the QNX 6.5 or QNX 6.6 toolchain, cmake threw the following error:

CMake Error at /usr/local/share/cmake-3.0/Modules/FindCurses.cmake:139 (CHECK_LIBRARY_EXISTS):
  Unknown CMake command "CHECK_LIBRARY_EXISTS".
Call Stack (most recent call first):
  TestProgram/curses/CMakeLists.txt:3 (find_package)

The same error is reproducible on cmake 3.0.2.




Steps To ReproduceTo reproduce the issue, you have to have a QNX 6.5 or QNX 6.6 toolchain installed.

1. Please create a simple cmake project which calls "find_package(Curses)"
project(test.curses)

find_package(Curses)

add_executable(${PROJECT_NAME} main.cpp)


2. In the main.cpp, it can just be an empty int main.

Additional InformationThe toolchains I am using are standard QNX 6.5 and QNX 6.6 toolchains downloaded from www.qnx.com.

The host OS is Ubuntu 12.04 64-bit.

Looks like CheckLibraryExists.cmake is included in one if() block while also being used in another if block with a different condition on it. CheckLibraryExists.cmake should probably be included unconditionally.

Re 0015220:0037076: Yes, unconditional inclusion is simpler. Done:

 FindCurses: Include CheckLibraryExists before using it

I've merged this to the 'release' branch for inclusion in the next 3.1 release candidate.
