It is unneeded to do it by target, using the globale property
CMAKE_CXX_STANDARD instead. Also with CMAKE_CXX_STANDARD_REQUIRED, I
make this a strong requirement. The documentation indeed states that the
CXX_STANDARD "is treated as optional and may “decay” to a previous
standard if the requested is not available".
This means that uchardet will likely not be buildable with a compiler
with no C++11 support. But I assume this is not a common situation, and
probably we should not care about outdated compilers. I remain open to
suggestions and disagreement on the topic obviously.
This way it always shows up in ccmake, even if not defined.
A string is used instead of path because I personally think it makes more
sense in the following use-cases:
STRING:
-DCMAKE_INSTALL_PREFIX=/home/user -DCMAKE_INSTALL_BINDIR=bins
installs everything to /home/user/{lib,etc,share,(...)} and executables to
${CMAKE_INSTALL_PREFIX}/bins
-DCMAKE_INSTALL_PREFIX=/home/user -DCMAKE_INSTALL_BINDIR=/opt/bin
everything to /home/user/{lib,etc,share,(...)} and executables to
/opt/bin
PATH:
-DCMAKE_INSTALL_PREFIX=/home/user -DCMAKE_INSTALL_BINDIR=bins
everything to /home/user/{lib,etc,share,(...)} and executables to
$(pwd)/bins (!)
-DCMAKE_INSTALL_PREFIX=/home/user -DCMAKE_INSTALL_BINDIR=/opt/bin
same as STRING
It is still ON by default, which means both shared and static libs will
be built and installed (current behavior), but it makes it possible to
disable the build of a static lib.
