[SOLVED] Source compiling help

Hello All

I am compiling qBittorrent in CentOS 8 from source. I want to compile binaries to /usr/local/bin and libraries to /usr/local/lib64 folder.

Compiling qBittorrent has 2 parts. 1) compile libtorrent-rasterbar and then 2) compile qBittorrent.

I successfully compiled part 1.
Code:$ wget https://github.com/arvidn/libtorrent/releases/download/libtorrent_1_2_7/libtorrent-rasterbar-1.2.7.tar.gz

$ tar xvf libtorrent-rasterbar-1.2.7.tar.gz

$ cd libtorrent-rasterbar-1.2.7/

$ ./configure --prefix=/usr/local --libdir=/usr/local/lib64 --disable-debug --enable-encryption CXXFLAGS="-std=c++14"

$ make -j4

$ sudo make install

# ls -lh /usr/local/lib64/

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables libtorrent_CFLAGS
and libtorrent_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.I believe I have to mention libtorrent-rasterbar's custom path while compiling.

How do I specify libtorrent-rasterbar's custom path in ./configure ... command?

Thanks
