<div>Hi,</div>
<div>currently I am working with cmake 3.9.0 on windows 10.</div>
<div>I want to use cmake to crosscompile some C sources with armclang.<br/>
The wiki page contains a section called "The toolchain file" (see <a href="https://deref-web-02.de/mail/client/di__f_6XC-c/dereferrer/?redirectUrl=https%3A%2F%2Fcmake.org%2FWiki%2FCMake_Cross_Compiling" target="_blank">https://cmake.org/Wiki/CMake_Cross_Compiling</a>).</div>
<div>My toolchain file looks as follows:</div>
<div>SET(CMAKE_SYSTEM_NAME Generic) # Target is an embedded system without OS<br/>
SET(CMAKE_SYSTEM_PROCESSOR arm) # The name of the cpu cmake is building for ARM</div>
<div>SET(CMAKE_C_COMPILER "C:/Program Files/ARMCompiler6.6.1/bin/armclang.exe")<br/>
SET(CMAKE_CXX_COMPILER "C:/Program Files/ARMCompiler6.6.1/bin/armclang.exe")<br/>
SET(CMAKE_ASM_COMPILER "C:/Program Files/ARMCompiler6.6.1/bin/armasm.exe")<br/>
SET(CMAKE_LINKER "C:/Program Files/ARMCompiler6.6.1/bin/armlink.EXE")<br/>
SET(FROMELF "C:/Program Files/ARMCompiler6.6.1/bin/fromelf.EXE")</div>
<div><br/>
The cmake execution leads to the following output:</div>
<div>==================================================================================================<br/>
A subdirectory or file CMakeMakefile already exists.<br/>
-- The C compiler identification is unknown<br/>

The CMakeError.log looks as follows:</div>

==================================================================================================</div>
<div>The compiler identification seems to fail.</div>
<div><br/>
Further on I was checking the possibility of "CMakeForceCompiler". But for version 3.9 this option is deprecated<br/>
(see <a href="https://deref-web-02.de/mail/client/dTI7icaMouo/dereferrer/?redirectUrl=https%3A%2F%2Fcmake.org%2Fcmake%2Fhelp%2Fv3.9%2Fmodule%2FCMakeForceCompiler.html%3Fhighlight%3Dcmakeforcecompiler" target="_blank">https://cmake.org/cmake/help/v3.9/module/CMakeForceCompiler.html?highlight=cmakeforcecompiler</a>)</div>
<div>The CMAKE_TRY_COMPILE_TARGET_TYPE was instead recommended.</div>
<div>In my case neither set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY) nor set(CMAKE_TRY_COMPILE_TARGET_TYPE EXECUTABLE) was working.<br/>
The error message was still the same.</div>
<div>Can you give me some advice?<br/>
How can I switch of the compiler checks?</div>
<div>Thanks a lot for your help.</div>
<div>Best regards.</div>
