Problem: QNX crosscompiler needs additional parameters to chosse the correct platform

Solution: Use a toolchain file for QNX x86

builds/qnx/ToolchainQNX6.6_x86.cmake

+set(CMAKE_SYSTEM_NAME QNX)
+
+set(arch gcc_ntox86)
+set(ntoarch x86)
+set(QNX_PROCESSOR x86)
+
+set(CMAKE_C_COMPILER qcc )
+set(CMAKE_C_COMPILER_TARGET ${arch})
+
+set(CMAKE_CXX_COMPILER QCC -lang-c++ -g)
+set(CMAKE_CXX_COMPILER_TARGET ${arch})
+
+set(CMAKE_ASM_COMPILER qcc -V${arch})
+set(CMAKE_ASM_DEFINE_FLAG "-Wa,--defsym,")
+
+set(CMAKE_RANLIB $ENV{QNX_HOST}/usr/bin/nto${ntoarch}-ranlib
+	    CACHE PATH "QNX ranlib Program" FORCE)
+    set(CMAKE_AR $ENV{QNX_HOST}/usr/bin/nto${ntoarch}-ar
+	        CACHE PATH "QNX qr Program" FORCE)
