The point of this file was to be easily usable by applications that want to generate capture files (or proxy them). The intention here is that we only have SpCaptureReader/SpCaptureWriter (and associated bits necessary to support that). This makes sure that we do not use GObject from the libsysprof-capture-2.a while still having GType's in the libsysprof-2.so dynamic library. We also invert the GObject macro check so that the default is to not register a GType which increases the chances that copy/paste code does not run into double-registering a GType if used with an application that links against libsysprof-2. (One such example could be if Gtk uses this code for timers, as it would break Sysprof itself).
Sysprof is a sampling profiler that uses a kernel module to generate
stacktraces which are then interpreted by the userspace program
"sysprof".

Debugging symbols
- The programs and libraries you want to profile should be compiled
with -fno-omit-frame-pointer and have debugging symbols available,
or you won't get much usable information.
Building Sysprof
----------------
You need some packages installed. The package names may vary depending on your
distribution, the following command works on Fedora 25:
sudo dnf install gcc gcc-c++ ninja-build gtk3-devel
Then do the following:
meson --prefix=/usr build
cd build
ninja
sudo ninja install
WARNING: `ninja install` will mostly install under the configured install
prefix but installs systemd service configuration directly in the system
default location `/usr/lib/systemd` so it won't work without root privileges,
even if the install prefix is a user-owned directory.
