[Proj] Failing to correctly configure, compile and run Proj locally

Greetings,
having recently cloned Proj from the Git repository at
https://github.com/OSGeo/proj.4.git
I want to configure, compile, and use it only locally in my home direct-
ory. For that I run the commands:
$ export PREFIX=$HOME PROD=proj
$ cmake -D CMAKE_BUILD_TYPE=RelWithDebInfo \
-D CMAKE_COLOR_MAKEFILE=OFF \
-D CMAKE_EXPORT_COMPILE_COMMANDS=ON \
-D CMAKE_INSTALL_PREFIX="$PREFIX" \
-D CMAKE_LEGACY_CYGWIN_WIN32=0 \
-D CONVERT_DATA=ON \
-D DATADIR="$PREFIX/share/$PROD" \
-D DOCDIR="$PREFIX/doc/$PROD" \
-D INCLUDEDIR="$PREFIX/include" \
-D LIBDIR="$PREFIX/lib" \
-D MANDIR="$PREFIX/man" \
-D PROJ_BIN_SUBDIR=bin \
-D PROJ_DATA_SUBDIR="share/$PROD" \
-D PROJ_DOC_SUBDIR="doc/$PROD" \
-D PROJ_INCLUDE_SUBDIR=include \
-D PROJ_LIB_SUBDIR=lib \
-LAH ..
$ cmake --build . --target all --target install
Apart from plenty of warnings regarding the redefinition of the constant
"M_TWOPI", the compilation succeeds. However, the resulting "proj" bin-
ary refuses to run as long as environment variable "PROJ_LIB" does not
explicitly hold the path to "share/proj/":
$ env|grep PROJ
$ proj +init=epsg:32661
Rel. 4.9.3, dd Month yyyy
<proj>:
projection initialization failure
cause: no system list, errno: 2
program abnormally terminated
$ export PROJ_LIB=$HOME/share/proj
$ proj +init=epsg:32661
^D
$
Is there a way to configure Proj in such a way that it's not necessary
to correctly set environment variable "PROJ_LIB" at runtime?
Any pointers welcome :-)
Sincerely,
Rainer
