What make command is used for try_compile?

Code

Hello,

I’m trying to create my own toolchain file, but I’m getting
a strange error message:

“[…] Run Build Command(s): -f Makefile cmTC_7ea91/fast […]”

Obviously before “-f” the make command is missing.

This only happens if I use “set(CMAKE_MAKE_PROGRAM /usr/bin/make)”.

What do I need to set to make cmake work?

Here’s my cmake command:

cmake -DCMAKE_TOOLCHAIN_FILE=…/tc.cmake …

Here’s the toolchain file:

set(CMAKE_FIND_ROOT_PATH /opt/avr)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)
set(CMAKE_MAKE_PROGRAM /usr/bin/make)

set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_PROCESSOR avr)
set(CMAKE_CROSSCOMPILING 1)

find_program(AVR_CC avr-gcc REQUIRED)
set(CMAKE_C_COMPILER ${AVR_CC})

Here’s the CMakeLists.txt:

cmake_minimum_required(VERSION 3.10)
project(problem C)
add_executable(simple simple.c)

Here’s the output of “cmake --version”:

cmake version 3.23.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

The system is a Linux Debian unstable.

And for completeness, here’s simple.c:

int main()
{
return 0;
}
