pip install conanCreate profiles for the available compilers.
# GCC is commonly the default compiler on Linux distributions
conan profile new --detect default
# Set properly CC and CXX to point respectively to the C and C++ compilers

Once you have configured the profiles, clone the repository.

mkdir build-dir && cd build-dir
# Run this script to export the conanfiles
../scripts/conan-bootstrap.bash
# You can list the available profiles you previously configured
conan profile list
# Build the dependencies
conan install --profile=default .. --build=missing
# Run CMake & Make

Debugging EFI applications has only been tested with GCC on Linux. It doesn't work with MINGW. It wasn't tested with Clang.
Start Qemu with the EFI binary without debug symbols. It will wait for a tcp connection on port 5555 before running OVMF.
make run-qemu-gdbstab
Start socat on port 5555.
make debug-tty
...
Image base: 0x<IMAGE_BASE>
Run gdb and load the image with debug symbols to a relocated address
make gdb
> efidebug -f binary-debug.efi -b 0x<IMAGE_BASE>
