Building to a specific directory

[brandoncc]

First off, thank you for this library.

I am attempting to use it in a heroku buildpack, and I'm having trouble building to a specific location.

This is how I build libheif:

ARG HEIF_VERSION=1.10.0
ARG HEIF_URL=https://github.com/strukturag/libheif/releases/download

RUN cd /usr/src \
  && wget ${HEIF_URL}/v${HEIF_VERSION}/libheif-${HEIF_VERSION}.tar.gz \
	&& tar xf libheif-${HEIF_VERSION}.tar.gz \
	&& cd libheif-${HEIF_VERSION} \
	&& ./autogen.sh \
	&& ./configure --prefix=/usr/src/vips --disable-gtk-doc \
	&& make \
	&& make install

I'm attempting to do the equivalent for libde265, so I did this:

ARG DE256_VERSION=1.0.8
ARG DE256_URL=https://github.com/strukturag/libde265/releases/download

RUN cd /usr/src \
  && wget ${DE256_URL}/v${DE256_VERSION}/libde265-${DE256_VERSION}.tar.gz \
	&& tar xf libde265-${DE256_VERSION}.tar.gz \
	&& cd libde265-${DE256_VERSION} \
	&& mkdir -p build \
	&& mkdir -p /usr/src/libde265 \
	&& cd build \
	&& cmake .. \
	&& make \
	&& DESTDIR=/usr/src/libde265 make install \
  && cp -R /usr/src/libde265/usr/local/* /usr/src/vips/

This didn't work as well as I had hoped. John (libvips author) has pointed out that it looks like pkgconfig can't find libde265.

For reference, here is my whole Dockerfile.

Could you please assist me in building the library in a way that will work for my use case? I found this line and these lines, which I think might be part of the solution. I don't know C/C++ though, so I don't know how to utilize them.

Thanks again.

John helped me get closer:

cd libde265
mkdir -p build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr/vips ..
make
make install

But, for some reason, libde265.pc isn't being created. Do you have any idea why?

I believe this is a stale issue that has been solved in the meantime. If you agree, I'm closing it.
