Hey ik0,

This is a two part problem.

First part is installing to a different prefix.
CMake builds take INSTALL_PREFIX argument. For Poppler it will be

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/home/ik0/pdf2htmlEX_and_deps -DCMAKE_BUILD_TYPE=Release -DENABLE_UNSTABLE_API_ABI_HEADERS=ON ..
make
make install

Autotools takes --prefix argument, so you can

./configure --prefix=/home/ik0/pdf2htmlEX_and_deps
make
make install

Second part is telling pdf2htmlEX to consume libraries from /home/ik0/pdf2htmlEX_and_deps and
Most libraries produce either pkg-config.pc or CMake find_package configs.
The former available in /usr/lib/pkgconfig, the latter in /usr/lib/cmake.

To find these libraries pdf2htmlEX uses pkg_check_modules, which internally uses pkg-config,
so that's the only one that we need to worry about right now.

First verify that you can find them manually.
pkg-config accepts PKG_CONFIG_PATH environment variable to tell it where it should look for .pc files first, before trying /usr/lib/pkgconfig . If I recall correctly one of these dependencies is installed to lib, other is to lib64, so we need to pass both.

PKG_CONFIG_PATH=/home/ik0/pdf2htmlEX_and_deps/lib/pkgconfig:/home/ik0/pdf2htmlEX_and_deps/lib64/pkgconfig pkg-config --cflags poppler libfontforge

Once you know that they're both installed "correctly", you can compile pdf2htmlEX with them

cd pdf2htmlEX_sources
mkdir build
cd build
PKG_CONFIG_PATH=/home/ik0/pdf2htmlEX_and_deps/lib/pkgconfig:/home/ik0/pdf2htmlEX_and_deps/lib64/pkgconfig cmake -DCMAKE_INSTALL_PREFIX=/home/ik0/pdf2htmlEX_and_deps ..
make

At this point you may be greeted by an error, which tells you that some header from poppler can't find "poppler/GfxState.h". Poppler's pkgconfig.pc file defines it's include path as /home/ik0/pdf2htmlEX_and_deps/include/poppler/ and this requested file would look like /home/ik0/pdf2htmlEX_and_deps/include/poppler/poppler/GfxState.h

Edit Poppler's pkgconfig.pc ( /home/ik0/pdf2htmlEX_and_deps/lib64/pkgconfig/poppler.pc ), so it includes the root include dir too.

CFlags: -I${includedir}/poppler

becomes

CFlags: -I${includedir}/poppler -I${includedir}

Try buildinging pdf2htmlEX again

cd pdf2htmlEX_sources
mkdir build
cd build
PKG_CONFIG_PATH=/home/ik0/pdf2htmlEX_and_deps/lib/pkgconfig:/home/ik0/pdf2htmlEX_and_deps/lib64/pkgconfig cmake -DCMAKE_INSTALL_PREFIX=/home/ik0/pdf2htmlEX_and_deps ..
make
make install

Try running the newly installed pdf2htmlEX

/home/ik0/pdf2htmlEX_and_deps/bin/pdf2htmlEX

You might get an error complaining about libpoppler.so not being found.

LD_LIBRARY_PATH=/home/ik0/pdf2htmlEX_and_deps/lib:/home/ik0/pdf2htmlEX_and_deps/lib64 /home/ik0/pdf2htmlEX_and_deps/bin/pdf2htmlEX

[Solved] Compile on Debian 10 buster #56
