Error running test executable: Cannot read test directory

[ryandesign]

Building litehtml 0.8 (with my fixes for #264 and #270) on macOS 12 fails for me with either external googletest 1.13.0:

CMake Error at /opt/local/share/cmake-3.24/Modules/GoogleTestAddTests.cmake:112 (message):
  Error running test executable.

or the bundled googletest:

I also have the same error. Do you have a solution?😉

@DUNDUN-ww Yes, the problem is here:

litehtml/test/render_test.cpp

Line 16 in 7b10cd5

const char* test_dir = "../test/render/"; // ctest is run from litehtml/build

As it says in the comment, it assumes that you are doing an out-of-source build in a directory created inside the source directory. In other words, in the top-level litehtml directory, do this:

mkdir build
cd build
cmake ..
make
make test

It will not work if you are doing an in-source build (in other words, if you do cmake . in the top-level litehtml directory) nor will it work if you are doing an out-of-source build but your build directory is not immediately inside the top-level litehtml directory. (In my case, my build directory was outside of the top-level litehtml directory.)
