AdaptiveCpp: Permission issue in manual build

Hello, I’m trying to build hipSYCL manually following the steps in README file.

git clone --recurse-submodules https://github.com/illuhad/hipSYCL
cd hipSYCL
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=. ..

and this is the output

then I tried to build it with: make install it causes fatal error:

make install
Scanning dependencies of target hipSYCL_cuda
[  2%] Building CXX object src/libhipSYCL/CMakeFiles/hipSYCL_cuda.dir/application.cpp.o
syclcc fatal error: [Errno 13] Permission denied: '/path/hipSYCL/bin/'
make[2]: *** [src/libhipSYCL/CMakeFiles/hipSYCL_cuda.dir/application.cpp.o] Error 255
make[1]: *** [src/libhipSYCL/CMakeFiles/hipSYCL_cuda.dir/all] Error 2
make: *** [all] Error 2

however the permissions for source and build directory have not changed since their creation and also /path/hipSYCL/bin/ exists and contains syclcc syclcc-clang.
