CMake and VCL application

[TotteKarlsson 1]

Hello,

Have anyone been able to ever build a VCL forms application using cmake?

 

Following the documentation here simply don't work.
 

Creating the simplest VCL application, with just the main form, and a CMake file that looks like this:

CMAKE_MINIMUM_REQUIRED(VERSION 3.0.0. FATAL_ERROR)

set_embt_target("VCL" "DynamicRuntime")
add_executable(DummyApp WIN32 arboreta.cpp TMainForm.cpp)

 

And configuring to build with any of Embarcaderos compilers, bcc32, bcc32c and or bcc32x, using either ninja or the "Borland Compiler" option, gives this linker error, and other messages:

The above linker error indicate that the linker thinks this is a command line application, with a main() function, instead of a WinMain one. 

This is after copying the Windows-Embarcadero.cmake file to CMakes install directory.

The problem is most likely in that file.

 

Anyone knowing how to get past the linker error and build a VCL forms application using CMake instead of the IDE?

 

Thanks,
