CMake 3.10.2 would report the following:

CMake Error at CMakeLists.txt:57 (INSTALL):
  INSTALL TARGETS given no RUNTIME DESTINATION for executable target
  "cbmconvert".

The RUNTIME DESTINATION attribute appears to be optional in some other
CMake versions (tested with 3.24.2). According to the documentation,
already the oldest CMake version that we intend to support (3.0.2)
recognizes that attribute.

Closes #2

FILE(WRITE) and FILE(READ) will treat CR and LF differently between
Microsoft Windows and POSIX. Avoid writing them, and adjust checksums.

Data files will be written in 192-byte blocks, with EOF being
indicated by a NUL byte. Any unused last bytes will be written as
they were in the previous 192-byte block (file name or previous
data block).

Also, use FILE(REMOVE ...) to remove files, and define
the macro EXECUTE_PROGRAM_EXPECT to expect failed execution.

Unfortunately, CMake cannot write a NUL byte to a file, so there does
not appear to be a way to test with a sector where all bytes are distinct.

In 1c58e3ba on CMake 3.14 or later,
we attempted to specify TYPE MAN for the manual pages.
There does not appear to be a way to specify a subdirectory
when using that notation. Let us revert to the older INSTALL
variant with explicit DESTINATION.

This error was pointed out by László Böszörményi (GCS).

In PROJECT, specify LANGUAGES C in order to avoid an
unnecessary implicit dependency on a C++ compiler.

In INSTALL, do not hard-code share/ in the paths, but rely on
INCLUDE(GNUInstallDirs) instead. The locations can be overridden by
CMAKE_INSTALL_DOCDIR and CMAKE_INSTALL_MANDIR.

We will also install cbmconvert.html in the documentation.

The cbmconvert version number is now specified in CMakeLists.txt.

In commit 50ba022e
we forgot to remove this artefact of the old build system.
