It's as easy as that. Cpptrace will automatically configure itself for your system.
Be sure to configure with `-DCMAKE_BUILD_TYPE=Debug`.

## Other Installation Mechanisms
@ -57,12 +59,33 @@ git clone https://github.com/jeremy-rifkin/cpptrace.git
mkdir cpptrace/build
cd cpptrace/build
cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=On
make
make -j
sudo make install
```
Using through cmake:
```cmake
include(CMakeFindDependencyMacro)
find_dependency(cpptrace REQUIRED)
target_link_libraries(<your target> cpptrace)
```
Be sure to configure with `-DCMAKE_BUILD_TYPE=Debug`.
Or compile with `-lcpptrace`:
```sh
g++ main.cpp -o main -g -Wall -lcpptrace
./main
```
If you get an error along the lines of
```
error while loading shared libraries: libcpptrace.so: cannot open shared object file: No such file or directory
```
You may have to run `sudo /sbin/ldconfig` so the system finds libcpptrace.so (I had to do this on Ubuntu).

### Local User Installation
To install just for the local user (or any custom prefix):
```sh
git clone https://github.com/jeremy-rifkin/cpptrace.git
# optional: git checkout <HASH or TAG>
mkdir cpptrace/build
cd cpptrace/build
cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=On -DCMAKE_INSTALL_PREFIX=$HOME/wherever
make -j
sudo make install
```
Using through cmake:
```cmake
find_package(cpptrace REQUIRED PATHS $ENV{HOME}/wherever)
target_link_libraries(<your target> cpptrace::cpptrace)
```
Using manually:
```
g++ main.cpp -o main -g -Wall -I$HOME/wherever/include -L$HOME/wherever/lib -lcpptrace
```
