cmake fails with clang related errors

[ghost]

Describe the bug I upgraded to image version 0E210 and tried to build Filer again from scratch. I checked out the repo, created a build directory and did cmake .. from within, but got this error:

hellochris% cmake ../              
-- The C compiler identification is Clang 10.0.1
-- The CXX compiler identification is Clang 10.0.1
-- Detecting C compiler ABI info

CMake Error at /usr/local/share/cmake/Modules/CMakeTestCCompiler.cmake:66 (message):
  The C compiler

    "/usr/bin/cc"

  is not able to compile a simple test program.

  It fails with the following output:

To Reproduce Steps to reproduce the behavior: Install version 0E210, check out Filer, attempt to run cmake

Before the change above, hello-0.5.0_0E213-FreeBSD-12.2-amd64.iso was 1.28 GB. After the change, hello-0.5.0_0E219-FreeBSD-12.2-amd64.iso is 1.27 GB. Some things I don't understand...

Thanks for reporting @moochris .

On 0E219+ (without deleting the .a files from the ISO) it compiles again. Probably deleting the .a files from the ISO was causing more hassle than it has advantages.

Oh OK, great - I will update
